NOTEHardware damage due to electromagnetic interferenceUsing the Industrial PC without functional earthing can lead to hardware damage due to electromagnetic in-terference.• Only use the device with functional earthing.

Electromagnetic compatibility (EMC) of the industrial PC includes on the one hand not affecting otherdevices and equipment by electromagnetic interference and on the other hand not being disturbed byelectrical or electromagnetic effects itself.

For this purpose, the Industrial PC must comply with certain protection requirements. The Industrial PC hasEMC interference immunity according to EN 61000-6-2. The EMC interference emission of the device meetsthe requirements of EN 61000-6-4.

The functional earth is necessary for the EMC of the device. The functional earth is established byconnecting the grounding point on the PC mounting plate to the central grounding point of the control cabinetin which the PC is installed.

4.3.3 Connecting cables and power supplyNOTE

Incorrect connection procedureIncorrect procedure when connecting the cables and the power supply can cause hardware damage.• Follow the documented procedure for connecting the cables and the power supply.• Always connect the cables first and only then switch on the power supply.• Please read the documentation for the external devices prior to connecting them.

NOTEConnection of incorrect battery packsThe connection of incorrect battery packs can lead to damage to the Industrial PC and to the battery packs.• Connect only Beckhoff battery packs to your Industrial PC.

Connecting cables

The connections are located in the front of the Industrial PC and are documented in Chapter 3.1 Structure[} 10].

Make sure that you first ground the PC (see Chapter Grounding of the Industrial PC [} 28]) and then plug inall data transfer cables.

Connecting the power supply

Cables with a maximum cable cross-section of 1.5 mm2 must be used for connecting the power supply. Toachieve the lowest possible voltage drop on the supply line, we recommend connecting the maximumpossible cross-section. In case of larger distances between the power source and the PC, take into accountthe voltage drop in relation to the cable cross-section as well as fluctuations in your supply voltage in order toensure that the voltage at the power supply unit does not fall below 22 V.

Proceed as follows to connect the 24 VDC power supply unit:

1. Check the correct voltage of your external power supply.2. Install the power cable.3. Plug the power cable into the voltage socket of the Industrial PC.4. Screw the power cable to the voltage socket of the Industrial PC.5. Connect the PC to your external 24 V power supply.6. Switch on the 24 V power supply.7. Measure the voltage on the power supply plug of the PC.

External battery pack and UPS output

If you ordered your device with an integrated UPS, then you can connect an external battery pack and installit on a DIN rail near to the PC. Use only Beckhoff battery packs for this:

• C9900-U330: Universal battery pack for PCs and Panel PCs in any configuration

When using the C9900-U330 battery pack, you can use the UPS output of the power supply unit (UPSOutput). The method of connecting different components can be taken from the wiring diagram in fig. 18.

So that the Industrial PC still has a monitor output in case of a power failure, a Control Panel can beconnected to the UPS output of the power supply unit. Even after a power failure there is a voltage of 24 VDCbetween the UPS output and the negative pole of the battery pack. The maximum load is 1.4 A (max. 2.5 Afrom year of manufacture 2016).

Once the PC has been de-energized via the UPS software, the UPS output is switched to 0 V. A connectedpanel is switched off.

Commissioning


4.4 Switching the Industrial PC on and offFirst switching on and driver installation

NOTEPublic networksConnecting the PC to public networks without additional protective measures can compromise the safety ofthe device.• Protect the PC before connecting it to public networks.

The Industrial PC is started when the system is switched on or when the power supply is connected.

When you switch on the Industrial PC for the first time, the pre-installed operating system (optional) will bestarted. For any additional hardware you have connected, you have to install the drivers yourself afterwards.In addition, the Beckhoff Device Manager starts automatically. The Device Manager is a software fromBeckhoff that supports you in configuring the PC.

If you have ordered the PC without an operating system, you must install this and the driver software for theadditional hardware you have connected and for the devices in the PC yourself. Please follow theinstructions in the documentation for the operating system and the additional devices.

Switching off the Industrial PC

NOTEData loss due to running softwareSwitching off the Industrial PC before the running software is terminated and the operating system is shutdown can lead to data loss.• Quit the running software and shut down the operating system before switching off the PC.

NOTEShortened battery life due to switching off the power supplyIf the power supply is simply switched off, the operating system shuts down via the battery. With daily use,this significantly shortens the life of the battery.• Avoid switching off the power supply before shutting down the operating system.• Use the Beckhoff concept (see below) to shut down the operating system in a battery-friendly manner.

When the system is switched off or disconnected from its own power supply, the Industrial PC is alsoswitched off.

If you have an Industrial PC with a UPS and simply switch off the power supply, the operating system shutsdown via the battery. With frequent use, this shortens the life of the battery.

To shut down the operating system properly, you can install an additional ON/OFF switch next to themachine's main switch to turn the machine on and off. The main switch can thus remain switched on inprinciple and thus ensures that the PC is still supplied with power during the shutdown of the operatingsystem.

If 24 V is then applied to the input PC_ON via a switch, the operating system shuts down properly. ThePC_ON signal is inverted, i.e. the operating system shuts down when 24 V is applied.

Once the operating system has shut down, the PC power supply unit sets the output power status from 24 Vto 0 V. This indicates that the shutdown is complete and you can turn off the power supply. Via the output,you can switch, for example, a contactor that switches off the entire system. The maximum load for thePower Status output is 0.5 A and a suitable fuse should be provided.

You can assign different access rights to all users in the operating system and in the application software.Since there is a risk of data loss if the Industrial PC is switched off incorrectly, assign the rights advisedly. Auser who is not allowed to terminate the software should not be allowed to switch off the Industrial PC.

UPS software components

Commissioning


To operate the power supply unit as a UPS, the UPS driver software with the corresponding drivers must beinstalled on the Industrial PC. The software and drivers are already installed on delivery of the PC withoperating system. Otherwise, you will have to install them yourself.

You can obtain the software and drivers either online for download via the following link: https://download.beckhoff.com/download/software/Industrial_PC/OS_Support/Driver_DVD or you can contactBeckhoff Service ([email protected]), which will provide you with the software and drivers. The driversoftware comes with a detailed help function. Call up the help files either directly from the configuration tabby clicking the Help button or start the file under Start > Programs > Beckhoff > UPS software components.

The method of communication between your PC and the UPS depends on the PC generation. The followingtable provides information about the method of communication according to the device generation:

Table 13: UPS communication

Device generation UPS communication methodC6920-0050 Serial communicationC6920-0060 Communication via BIOS APIC6920-0070 Communication via BIOS API

In the case of serial communication, all you need is the UPS driver. If the communication takes place via theBIOS API, you also need the Beckhoff Automation Device Driver in addition to the UPS driver.

Only the manufacturer may repair the device. If a repair should be necessary, contact Beckhoff Service (seeChapter 10.1 Service and support [} 48]).

7.1 CleaningNOTE

Unsuitable cleaning agentsThe use of unsuitable cleaning agents can damage the device.• Only clean the Industrial PC as specified.

It is essential to observe the following aspects when cleaning the Industrial PC:

• Make sure that no dust gets into the PC.• Always keep the ventilation grilles free.• Only use a vacuum cleaner to clean the PC. The Industrial PC does not have to be switched off for

this.• Never use compressed air to clean the PC.

Maintenance


7.2 MaintenanceNOTE

Use of incorrect spare partsThe use of spare parts not ordered from Beckhoff Service can lead to unsafe and faulty operation.• Only use spare parts that you have ordered from Beckhoff Service.

Beckhoff Industrial PCs are manufactured from components of the highest quality and robustness. They areselected and tested for best interoperability, long-term availability and reliable function under the specifiedenvironmental conditions.

Nevertheless, some components of the Industrial PC may be subject to a limited service life if they areoperated under certain conditions, such as more demanding ambient conditions during operation or duringstorage, or if they are out of service for long periods of storage.

Beckhoff therefore recommends replacing some of the Industrial PC components after the time after whichpredictions of the remaining service life of such components can no longer be reliably calculated.

These are the following components:

• Battery and battery pack• Storage media• Fan

The following table provides recommendations for the regular, precautionary replacement of the PCcomponents:

Table 14: Replacement recommendations for PC components

Component Recommendation for replacement intervals (years)UPS battery pack 5 years2.5-inch hard disk 5 years or after 20,000 operating hours at more than 40 °C or after

Beckhoff is excluded from liability in the event of possible damage occurring during maintenance work. Inorder to avoid damage caused by electrostatic discharge when replacing device components, protectivemeasures are recommended. Below are some suggestions.

ESD protection

NOTEElectrostatic dischargeThe replacement of device components without ESD protection can lead to functional impairment and de-struction of the device.• If possible, apply ESD protection measures during maintenance work.

When working on electronic devices, there is a risk of damage due to ESD (electrostatic discharge), whichcan impair the function or destroy the device.

Protect the Industrial PC and create an ESD-protected environment in which any electrostatic charges aredischarged to the ground in a controlled manner and charging is prevented.

An ESD-protected environment can best be created by setting up ESD protection zones. The followingmeasures serve this purpose:

• ESD-compliant floors with sufficient conductivity to the reference potential PE;• ESD-compatible work surfaces such as tables and shelves;

Maintenance


• Wrist grounding strap, especially for sedentary activities;• grounded and electrostatically dissipating equipment and operating materials (e.g. tools) within the

ESD protection zone.

If it is not possible to create an ESD protection zone, you can still protect the device against ESD damage.For example, the following measures can be used:

• Use conductive mats connected to the ground potential as underlays.• Dissipate possible charges from your own body by touching earthed metal (e.g. control cabinet door).• Wear a wrist grounding strap.• Only remove new electronic components from the ESD packaging (tinted plastic bag) after putting on

the wrist grounding strap.• Do not walk around with electronic components in your hand if they are not in ESD packaging.

Maintenance

7.2.3 Replacing the storage mediaNew storage media should only be obtained from Beckhoff Service (see Chapter 10.1 Service and support[} 48]).

The old storage media must be disposed of in accordance with the national electronic waste regulations.

Data transfer before replacement

If you want to exchange a storage medium according to Beckhoff's recommendation, you must copy the datafrom the old to the new storage medium. You can use the Beckhoff Service Tool (BST) for this purpose. TheBST is a graphical backup and restore program for Industrial PCs with a Windows operating system. Youcan create an image of your operating system and use it to back up the operating system. You can thenrestore the images created in this way. The BST is available on a bootable BST USB flash drive. Thisincludes Windows and a backup software. Select the size of the BST USB flash drive according to the size ofthe backup copy of your operating system. You can then keep the flash drive as a backup copy. For thispurpose, the BST USB flash drives with SLC flash are designed for a particularly long data preservation. Formore information on the function of the BST, please refer to the corresponding documentation.

If your storage medium is defective and there is no backup, Beckhoff Service can provide you with a freshWindows image. For this to be possible, the Beckhoff IPC must already have been shipped with a validoperating system license. When installing the fresh image, the applications must be reinstalled.
